    Ok, after Johannes sent me his data map, I figured what it is.
    "adresse" DbEntity has both an attribute and a relationship called
    "PLZ"! So Cayenne gets confused, leading to unpredictable and hard to
    trace errors. Please rename either the attribute or relationship. On
    our part, I guess we should add this validation to the modeler. I'll
    open a bug for that. Very annoying error indeed!
